ARTIFTCIAL STONE.

SPECIFICATION forming part of Letters Application filed Januury15,18 t=fi.

To all 207mm it may concern:

Be it known that I, HENRY AfDANIELs, a citizen of the United States, and a resident of Yonkers, in the county of 'estchester and State of New York, have invented certain new and useful Improvements in Artificial Stone, of which the following is a specification.

My invention relates to the production of an artificial stone capable of being formed from a plastic material which acquires great hardness and solidity after it has become set and dried, and which will successfully resist the influence of varying temperatures and the efi'ects of moisture, and which may be employed as a substitute for natural stone and marble.

In the preparation of my improved artificial stone 1 use a body material consisting of sand, or in some cases of other refractory finelygranulated substanceas crushed "ravel, iii mile d 11st,, brick dust &c.and cemen'i,

lid with this comoine a binding material, which I have found in practice to impart great solidity, hardness, and toughness to the artificial composition. This binding material may be any suitablcsoft non-friablegumin solution, or a solution of mueilaginous substance-as, for instance, a solution of caoutchonc orglue. I prefer to use a solution of caoutchouc, and in some instances to use in connection there with asolution of gum or glue. In some instances I combine with the above-named substances iearlash, niuriate of soda, white or blue vi or soluIIIe Iass. or eltherol them, and with either 0? all of said substances I also add, in some instances, a proportion of alum, and to the composition 1 add any suitabIecoI- oring-matter, according to the colors I desire to impart to the stone and the purpose for which it is to be employed. The cement used will also depend upon the purpose for which the stone is employed and the color required, Keenes cement being preferably used when t e composition is to be ofa light color, and Martins cement, or Portland cement, or any other cement Being substituted therefor'when desired.

In the preparation of the stone I mix the Serial No. 15 8.673. (No specimenVJZ Patent No. 346,729, dated August 3, 1886.

body materialsas sand and cement-dry with the coloring material,aud then gradually add the solution, working the whole together un til a paste-like mixture is made ofpro wrconsistency to be applied to any desired surface with a trowel, or to be cast or molded.

\Vhile I have referred to the use of pearlash and other materials named in connection with the body material and the binding material, I do not here claim the use of these ingredients, as the mixture embodying them constitutes the subjects of separate applica- 0 tions for Letters Patent, and I only name them in order to set forth some of the applications to which the improved composition may be put in the manufacture of artificial stone.

The ingredients specified may be used in 6 different proportions; butI prefer to use sand and cement in suitable proportions-as, for instance, ten pounds of sand. five pounds of cement. and one-fourth oI a pound of gum I glue, or caoutchouc to each gallon of liqnid t 1e solution,as aloresaid, being added to the pnlverized-materials in sufficient quantities to make a paste of the stiffness desired. The solvent used will of course depend upon the character of the ingredient water being used 5 for dissolving glue,and naphtha or its equivalent for dissolving the gum.

Without limiting myselfto the precise proportions set forth, I claim- 1. An artificial-stone composition consisting of sand, cement, and a solution of eaoutehouc 0r non-friable binding material, substantially as set forth.

2. An artificial stone consisting of sand, cement, and a non-friable binding material- U such as caoutchouc-combincd substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

HENRY A DANIELS.
